Wilshere, now a free agent, and Juventus midfielder Ramsey both had lengthy spells out injured at Arsenal, with Wilshere missing the entire 2011-12 campaign with a stress fracture in his ankle, while Ramsey's leg was broken following a challenge from Ryan Shawcross while playing against Stoke in 2010.
Wenger told The Telegraph: "I see more positivity. Before there was more kicking and I must say the media allowed that. The VAR has brought more respect for the offensive game.
"Sometimes the more technical guys were kicked. Why? It was not very encouraging. We have moved forward from that.
"We always tried. It was a frustration sometimes. When I look back at players like Wilshere, Ramsey who have been injured early in their career and when you are a manager you feel very responsible for that."
